Description

本発明は、電線接続装置に関し、詳しくは、複数本の導電線同士を容易に導通接続させ、また、その導通接続を容易に解消するとともに再利用することのできるものに関する。   The present invention relates to an electric wire connection device, and more particularly, to an apparatus that allows a plurality of conductive wires to be easily conductively connected, and that the conductive connection can be easily eliminated and reused.

従来、電線同士を接続する場合には、被覆を剥いだ導電線に圧縮スリーブを被せて圧着結合させることにより電気的に導通接続することが行われており、例えば、既設の電線に別個の電線を導通接続して分岐させる場合には、既設電線の分岐箇所の被覆を剥ぐと共に分岐電線の先端部の被覆を剥いでその導電線同士を断面O形状の圧縮スリーブ(圧縮端子)内で一緒に圧着結合させることにより導通接続させている(例えば、特許文献1参照)。   Conventionally, when wires are connected to each other, an electrically conductive connection is performed by applying a compression sleeve to a conductive wire from which the coating has been peeled off and then crimping and bonding. For example, a separate wire is connected to an existing wire. When branching by connecting the conductors, the covering of the branch portion of the existing electric wire is peeled off and the tip of the branch electric wire is peeled off, and the conductive wires are joined together in a compression sleeve (compression terminal) having an O-shaped cross section. Conductive connection is established by pressure bonding (for example, see Patent Document 1).

また、他の接続構造としては、既設電線と分岐電線の導電線をそれぞれ収装可能に断面8字形状に形成されている圧縮端子も提案されており、この圧縮端子では、既設電線と分岐電線の導電線を断面8字形状のそれぞれ異なる収装穴内に収装させて別個に圧着結合させることにより導通接続させている(例えば、特許文献2参照)。   As another connection structure, there has also been proposed a compression terminal formed in an 8-shaped cross section so that the conductive wires of the existing electric wire and the branch electric wire can be accommodated respectively. In this compression terminal, the existing electric wire and the branch electric wire are provided. These conductive wires are housed in different housing holes each having an 8-shaped cross section and are separately connected by pressure bonding (for example, see Patent Document 2).

さらに、主電線に分岐電線を複数本接続して分岐させる場合、例えば、図8に示すように、電柱101の変圧器103の低圧側に接続した引下電線107に各家庭などに電気を配電する引込電線を分岐接続する場合には、図9および図10に示すように、複数の端子T1〜T5を内装する分岐ボックス110をその電柱101の腕金105に取り付けて、その端子T5に引下電線107をネジ止めして導通接続すると共に端子T1〜T4に引込電線をネジ止めして導通接続させることにより、引下電線107に引込電線を分岐接続することができる(例えば、特許文献3参照)。なお、図8や図9中における106は電柱101の腕金105に分岐ボックス110を取り付ける取付金具であり、また、112はその引込分岐ボックス110内の端子T1〜T5を露出させてネジ止め作業を行う際に開閉するカバーである。

Furthermore, when branching by connecting a plurality of branch wires to the main wire, for example, as shown in FIG. 8, electricity is distributed to each household or the like on the drawn-down wire 107 connected to the low voltage side of the transformer 103 of the utility pole 101. 9 and 10, the branch box 110 having a plurality of terminals T1 to T5 is attached to the arm metal 105 of the utility pole 101 and pulled to the terminal T5. The lower electric wire 107 is screwed and conductively connected, and the drawn electric wire is screwed and electrically connected to the terminals T1 to T4, whereby the drawn electric wire can be branched and connected to the lower electric wire 107 (for example, Patent Document 3). reference). In FIG. 8 and FIG. 9, reference numeral 106 denotes a mounting bracket for attaching the branch box 110 to the arm metal 105 of the utility pole 101, and 112 denotes a screwing operation by exposing the terminals T1 to T5 in the pull-in branch box 110. It is a cover that opens and closes when performing.

しかしながら、このような従来の電線接続装置にあっては、主電線に複数本の電線を分岐させる場合には、文献3に記載の分岐ボックス110を用いればよいが、例えば、電気の配電先の増加に伴って、分岐する引込電線の接続数がその分岐ボックス110内に準備されている端子Tを超える場合には、主電線の引下電線107を別途準備すると共に分岐ボックス110自体を増設しなければならない。   However, in such a conventional wire connecting device, when a plurality of wires are branched to the main wire, the branch box 110 described in Document 3 may be used. As the number of lead-in wires branching out increases, the number of connected lead wires exceeds the terminal T prepared in the branch box 110, and the main wire pull-down wire 107 is separately prepared and the branch box 110 itself is added. There must be.

また、この分岐ボックス110は、全ての種別の電線を端子Tに接続可能に準備されておらず、そのような場合には、文献1や文献2に記載の圧縮端子を用いて引下電線107に引込電線を導通接続させるしかない。このような圧縮端子は、専用工具が必要であり、作業が煩雑であるとともに、一旦結合させてしまうと外すことができないために、再利用することができず、また、不要になった場合には、引下電線107を切断したり、交換しなければならない。   Further, the branch box 110 is not prepared so that all types of electric wires can be connected to the terminal T. In such a case, the pull-down electric wires 107 are used by using the compression terminals described in the literatures 1 and 2. There is no choice but to connect the lead-in wire to the conductor. Such a compression terminal requires a dedicated tool, is cumbersome, and cannot be removed once it has been joined, so it cannot be reused and is no longer needed. Needs to cut or replace the drawn wire 107.

そこで、本発明は、複数本の導電線同士を容易に導通接続させることができるとともに、また、再利用可能に取り外してその導通接続を容易に解消することのできる電線接続構造を実現することにより、例えば、主電線に複数本の電線を適宜導通接続して分岐させる一方、その主電線を切断などすることなく、再利用可能にその分岐接続を解消することのできる電線接続装置を提供することを目的とする。   Therefore, the present invention realizes an electric wire connection structure that can easily connect a plurality of conductive wires to each other and that can be removed for reuse and easily eliminate the conductive connection. For example, to provide an electric wire connecting device that can branch a main electric wire by appropriately connecting and branching a plurality of electric wires while reusing the main electric wire without cutting the main electric wire. With the goal.

上記課題を解決する電線接続装置の第1の発明は、雄ネジ部材と雌ネジ部材を螺合させて相対回転させることにより互いの間隔を接離させる一対の接続端子が同一径または異径の複数本の導電線毎に準備されて、該導電線のそれぞれに直接圧接接続する接続端子を介して当該導電線を電気的に導通接続させる電線接続装置であって、雄ネジ部材の軸心に対して同一の略直交方向に延在するように取り付けられて該雄ネジ部材と雌ネジ部材の螺合回転方向に応じて接離する3枚以上で一組の接続端子を備えており、挟まれている状態の共通接続端子や外面側の外側接続端子の接続端子間で導電線のそれぞれに直接圧接接続することを特徴とするものである。   According to a first aspect of the electric wire connecting apparatus for solving the above problems, the pair of connecting terminals that are brought into and out of contact with each other by screwing the male screw member and the female screw member to make a relative rotation have the same diameter or different diameters. An electric wire connecting device that is prepared for each of a plurality of conductive wires, and that electrically connects the conductive wires through connection terminals that are directly press-connected to each of the conductive wires. It is provided with a set of three or more connection terminals that are attached so as to extend in the same substantially orthogonal direction and come into contact with or separate from each other according to the screwing rotation direction of the male screw member and the female screw member. It is characterized in that the conductive wires are directly press-contacted between the connection terminals of the common connection terminals in the connected state and the outer connection terminals on the outer surface side.

この発明では、被覆電線あるいは裸電線の複数本の導電線毎に、共通接続端子と外側接続端子の間や共通接続端子間に挟み込むようにそれぞれの接続端子を雄ネジ部材と雌ネジ部材により接近させることができ、その導電線のそれぞれを圧接接続する接続端子を介して導通接続させることができる。したがって、接続端子の間に導電線を位置させて雄ネジ部材と雌ネジ部材を締め付ける方向に螺合回転させるだけで複数本の導電線を導通接続することができ、反対に、その雄ネジ部材と雌ネジ部材を緩める方向に螺合回転させるだけでその接続端子の間から導電線を離脱させて外すことができる。   In this invention, for each of the plurality of conductive wires of the covered wire or the bare wire, the connection terminals are brought closer to each other by the male screw member and the female screw member so as to be sandwiched between the common connection terminal and the outer connection terminal or between the common connection terminals. Each of the conductive wires can be conductively connected via a connection terminal for press-connecting the conductive wires. Accordingly, a plurality of conductive wires can be conductively connected simply by positioning a conductive wire between the connection terminals and screwing and rotating the male screw member and the female screw member in a tightening direction. By simply screwing and rotating the female screw member in the loosening direction, the conductive wire can be detached from the connection terminals and removed.

上記課題を解決する電線接続装置の第2の発明は、上記第1の発明の特定事項に加え、前記接続端子は、延在方向の両端部側に雄ネジ部材と雌ネジ部材が配設されて外側接続端子をそれぞれ共通接続端子に対して接離させることを特徴とするものである。   According to a second aspect of the electric wire connecting apparatus for solving the above problems, in addition to the specific matters of the first aspect, the connection terminal has a male screw member and a female screw member disposed on both end sides in the extending direction. The outer connection terminals are brought into contact with and separated from the common connection terminals.

この発明では、外側接続端子の両端部側が雄ネジ部材と雌ネジ部材により接離されて共通接続端子と外側接続端子の間や共通接続端子間で導電線を両側から均等に挟み込んで圧接させることができる。したがって、接続端子を導電線に安定して圧接させて導通接続させることができる。   In this invention, both end portions of the outer connection terminal are contacted and separated by the male screw member and the female screw member, and the conductive wires are evenly sandwiched from both sides and pressed between the common connection terminal and the outer connection terminal or between the common connection terminals. Can do. Therefore, the connection terminal can be stably brought into pressure contact with the conductive wire and conductively connected.

上記課題を解決する電線接続装置の第3の発明は、上記第1または第2の発明の特定事項に加え、前記接続端子は、延在方向に対して交差する方向に開口する湾曲形状に形成されて該湾曲形状内に導電線を収装して圧接することを特徴とするものである。   According to a third aspect of the electric wire connecting apparatus for solving the above problems, in addition to the specific matter of the first or second aspect, the connection terminal is formed in a curved shape that opens in a direction intersecting the extending direction. Then, the conductive wire is accommodated in the curved shape and press-contacted.

この発明では、接続端子に対する交差方向に導電線を延長させてその接続端子に湾曲形状内で圧接させて導通接続させることができる。したがって、接続端子に対する交差方向に導電線を並列させて導通接続させることができる。   In the present invention, the conductive wire can be extended in the crossing direction with respect to the connection terminal and brought into pressure contact with the connection terminal in a curved shape to be conductively connected. Therefore, the conductive wires can be connected in parallel in the crossing direction with respect to the connection terminal to be conductively connected.

上記課題を解決する電線接続装置の第4の発明は、上記第1から第3のいずれかの発明の特定事項に加え、前記接続端子の複数組の収容空間を絶縁材料よりなるケース部材の端辺同士を接離させることにより開閉するケースを備えており、ケース部材の端辺には、接続端子が圧接して導通接続する電線に圧接して保持する保持手段が設けられていることを特徴とするものである。   According to a fourth aspect of the electric wire connecting apparatus for solving the above-mentioned problems, in addition to the specific matter of any one of the first to third aspects, an end of a case member made of an insulating material is provided with a plurality of accommodation spaces of the connection terminals. It is provided with a case that opens and closes by bringing the sides into contact with each other, and holding means is provided on the end side of the case member to hold the connection terminal in pressure contact with the electric wire to be conductively connected. It is what.

この発明では、複数本の導電線毎に圧接させて導通接続させた1組または2組以上の接続端子をケース内に収容するとともに、そのケース部材の端辺間にその複数本の導電線を圧接させて位置決め保持させることができる。したがって、導電線や接続端子の導通部分をケース内に収容して絶縁性を確保することができるとともに、その接続端子の近傍で導電線が揺動して応力集中により断線等を生じさせてしまうことを未然に防止することができる。   In this invention, one set or two or more sets of connection terminals that are press-contacted and conductively connected for each of a plurality of conductive wires are accommodated in the case, and the plurality of conductive wires are arranged between the edges of the case member. It can be pressed and held in position. Therefore, the conductive portion of the conductive wire and the connection terminal can be accommodated in the case to ensure insulation, and the conductive wire swings in the vicinity of the connection terminal, causing disconnection or the like due to stress concentration. This can be prevented beforehand.

上記課題を解決する電線接続装置の第5の発明は、上記第4の発明の特定事項に加え、前記保持手段として、ケース部材の端辺の一方または双方に、互いに接離する方向に延長されてケース部材の端辺間の空間を概略閉止するヒダ状部材、あるいは、互いに圧接して弾性変形する弾性部材が配設されていることを特徴とするものである。   According to a fifth aspect of the electric wire connecting apparatus for solving the above-mentioned problems, in addition to the specific matter of the fourth aspect of the invention, as the holding means, one or both of the end sides of the case member are extended in the direction of contacting or separating from each other. A pleated member that substantially closes the space between the edges of the case member or an elastic member that is elastically deformed by being pressed against each other is provided.

この発明では、ケース部材を開閉するだけで複数本の導電線をそれぞれヒダ状部材間に進入させて、あるいは、弾性変形する弾性部材間に圧接させて位置決め保持することができる。したがって、接続する導電線の本数を制限することなく、ケース内に導電線を位置決め保持しつつ収容して絶縁性を確保することができる。   In the present invention, it is possible to position and hold a plurality of conductive wires by allowing them to enter between pleated members or by pressing between elastic members that are elastically deformed by simply opening and closing the case member. Therefore, without restricting the number of conductive wires to be connected, the conductive wires can be accommodated in the case while being positioned and secured to ensure insulation.

このように本発明によれば、複数本の導電線のそれぞれを共通接続端子や外側接続端子の間に挟み込むように雄ネジ部材と雌ネジ部材により容易に圧接させて導通接続させることができ、また、その雄ネジ部材と雌ネジ部材による締付を緩めるだけで導電線から接続端子を外すことができる。したがって、複数本の導電線同士の導通接続とその解消を容易に行うことができ、その導電線を切断する必要はなく、また、その接続端子も再利用することができる。また、複数組の接続端子を用いることにより、1本の導電線に2本以上の導電線を分岐接続することもでき、電線分岐装置を構成することができる。   Thus, according to the present invention, each of the plurality of conductive wires can be easily press-contacted by the male screw member and the female screw member so as to be sandwiched between the common connection terminal and the outer connection terminal, and can be conductively connected. Further, the connection terminal can be removed from the conductive wire simply by loosening the tightening by the male screw member and the female screw member. Therefore, the conductive connection between a plurality of conductive lines and the cancellation thereof can be easily performed, the conductive lines need not be cut, and the connection terminals can be reused. Further, by using a plurality of sets of connection terminals, two or more conductive wires can be branched and connected to one conductive wire, and an electric wire branching device can be configured.

以下、本発明の最良の実施形態を図面に基づいて説明する。図1〜図7は本発明に係る電線接続装置の一実施形態を示す図である。   DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, the best embodiment of the invention will be described with reference to the drawings. 1-7 is a figure which shows one Embodiment of the electric wire connection apparatus based on this invention.

図1において、電線接続装置10は、引下電線107や引込電線108の導電線107a、108aに圧接接続する各電線毎の接続部11と、この接続部11と共に接続した引下電線107や引込電線108を収容するケース21と、を備えており、電気を配電する各家庭などの戸数に応じた数の引込電線108を、図8に示す電柱101の変圧器103の低圧側に接続する引下電線107に接続部11を介して分岐接続してケース21内に収容することによりその電柱101の腕金105に取り付けて支持させることができる。   In FIG. 1, the electric wire connecting device 10 includes a connecting portion 11 for each electric wire that is press-contacted to the conductive wires 107 a and 108 a of the drawn down electric wire 107 and the drawn-in electric wire 108, and the drawn down electric wire 107 and the drawn-in wire connected together with the connecting portion 11. And a case 21 for housing the electric wire 108, and the number of the drawn electric wires 108 corresponding to the number of households in each household that distributes electricity is connected to the low voltage side of the transformer 103 of the utility pole 101 shown in FIG. By branching and connecting to the lower electric wire 107 via the connecting portion 11 and accommodated in the case 21, it can be attached to and supported by the arm metal 105 of the electric pole 101.

接続部11は、図2に示すように、長尺な導電性板材料を接続対象の引下電線107や引込電線108の線径サイズに応じて加工されている3枚一組の接続端子12〜14を備えており、この接続端子12〜14は、図3に示すように、その両端側に連結穴12a〜14aが開口する概略長方形に形成されて、それぞれの連結穴12a〜14aにナット(雌ネジ部材)Nの螺合するボルト(雄ネジ部材)Bを貫通させることにより互いの対向面を接離させることのできる両端支持構造に設計されている。ここで、本実施形態では、接続端子12〜14の両端部をネジ止めする両端支持構造の場合を一例に説明するが、これに限るものではなく、例えば、連結穴12a〜14aを一端側のみにして片持ち構造にしてもよいことは言うまでもない。   As shown in FIG. 2, the connection portion 11 is a set of three connection terminals 12 in which a long conductive plate material is processed according to the wire diameter size of the drawn down electric wire 107 and the drawn-in electric wire 108 to be connected. As shown in FIG. 3, the connection terminals 12 to 14 are formed in a substantially rectangular shape having connection holes 12 a to 14 a opened at both ends thereof, and nuts are provided in the connection holes 12 a to 14 a. (Female thread member) It is designed to have a both-end support structure in which the opposing surfaces can be brought into contact with each other by penetrating a bolt (male thread member) B into which N is screwed. Here, in the present embodiment, a case of a both-end support structure in which both ends of the connection terminals 12 to 14 are screwed will be described as an example. However, the present invention is not limited to this. For example, the connection holes 12a to 14a are only on one end side. Needless to say, a cantilever structure may be used.

接続端子12〜14は、両端側の連結穴12a〜14aにボルトBが貫通することによりそのボルトB間でその軸心に対して略直交方向に延在する姿勢になるように組み立てられており、その外側の接続端子12、14の間に位置する接続端子13を共通にして互いの対向面を接離させている。   The connection terminals 12 to 14 are assembled so that the bolts B pass through the connecting holes 12a to 14a on both ends, so that the connection terminals 12 to 14 extend in a direction substantially orthogonal to the axis between the bolts B. The connection terminals 13 located between the outer connection terminals 12 and 14 are shared, and the opposing surfaces are separated from each other.

この共通接続端子13は、その連結穴13a間を含めて平板形状に形成されているのに対して、外側接続端子12、14は、その連結穴12a、14aから離隔するに従って互いの対向面同士を離隔させた後に接近するように湾曲しており、この接続端子12〜14は、その延在方向に対する直交方向に延長されている引下電線107や引込電線108の導電線107a、108aを収装して圧接可能に開口する湾曲形状を互いの対向面間に形成する端子形状に形成されている。   The common connection terminal 13 is formed in a flat plate shape including between the connection holes 13a, whereas the outer connection terminals 12 and 14 face each other as they are separated from the connection holes 12a and 14a. The connection terminals 12 to 14 accommodate the conductive wires 107a and 108a of the pull-down electric wire 107 and the lead-in electric wire 108 that are extended in a direction orthogonal to the extending direction. It is formed into a terminal shape that forms a curved shape that opens so as to be press-contactable between the opposing surfaces.

これにより、接続部11は、図4に示すように、ボルトBをワッシャWに続けて接続端子12〜14の連結穴12a〜14a内に順次に貫通させて互いに対面させつつそのボルトBにナットNを螺合回転させることにより、接続端子12〜14の互いの対向面間の間隔を短くして接近させ、その対向面内の湾曲形状の内面12b、13bと内面13c、14cのそれぞれの間に外被を剥いだ引下電線107や引込電線108の導電線107a、108aを並列させた状態で収装して両端側から均等に圧接させることができ、その引下電線107と引込電線108を接続端子12〜14やボルトBを介して安定した状態で確実に導通接続することができる。このとき、接続端子12〜14は、ボルトBとナットNにより締め付けて変形させることによって連結穴12a〜14aの開口する両端部側の外面同士を圧接させる構造に設計しても良く、これにより、その引下電線107と引込電線108を接続端子12〜14を介して導通接続させるように作製することもできる。   As a result, as shown in FIG. 4, the connecting portion 11 allows the bolt B to pass through the washer W sequentially into the connecting holes 12a to 14a of the connecting terminals 12 to 14 and face each other while the nut is attached to the bolt B. By screwing N, the distance between the facing surfaces of the connection terminals 12 to 14 is shortened and brought close to each other, and between the curved inner surfaces 12b and 13b and the inner surfaces 13c and 14c in the facing surface, respectively. The drawn down electric wire 107 with the outer sheath peeled off and the conductive wires 107a, 108a of the drawn-in electric wire 108 can be accommodated in a parallel state and pressed uniformly from both ends. Can be securely connected in a stable state via the connection terminals 12 to 14 and the bolts B. At this time, the connection terminals 12 to 14 may be designed to have a structure in which the outer surfaces on both end sides of the connection holes 12a to 14a are pressed to each other by being tightened and deformed by the bolts B and nuts N. It is also possible to produce the drawn-in electric wire 107 and the drawn-in electric wire 108 so as to be conductively connected through the connection terminals 12 to 14.

よって、電線接続装置10は、図5に示すように、引下電線107に接続する引込電線108の本数に応じて、その外被を剥いで接続部11により適宜導通接続させることができる。   Therefore, as shown in FIG. 5, the wire connecting device 10 can peel off the outer cover and make the conductive connection appropriately by the connecting portion 11 in accordance with the number of the drawn-in wires 108 connected to the drawn-down wires 107.

ここで、この接続部11は、外側接続端子12、14の異なる湾曲形状の内面12b、14cを引下電線107と引込電線108の導電線107a、108aに圧接させて導通接続するが、これに限るものではなく、その導電線107a、108aの線径が大きく異なることなく一方で圧接接続させることができる場合には、その湾曲形状が共通になるように形成しても良く、また、さらに大径あるいは小径の導電線を圧接接続させることができるように、別個の接続端子を準備してもよいことはいうまでもない。   Here, the connecting portion 11 is in conductive connection by pressing the inner surfaces 12b and 14c having different curved shapes of the outer connection terminals 12 and 14 to the conductive wires 107a and 108a of the lead-in wire 107 and the lead-in wire 108. The present invention is not limited to this, and the conductive wires 107a and 108a may be formed so as to have a common curved shape if they can be press-contacted without greatly differing in wire diameter. It goes without saying that a separate connection terminal may be prepared so that a conductive wire having a diameter or a small diameter can be press-connected.

ケース21は、図6に示すように、例えば、絶縁性を有する樹脂材料を2つ割り可能な概略直方体に成形することにより作製されており、その2つ割りしたケース部材22の端辺22a同士を突き合わせることにより、1本の引下電線107に複数本の引込電線108を接続する複数組の接続端子12〜14(接続部11)をその引下電線107や引込電線108と共に収容する空間を形成するように設計されている。   As shown in FIG. 6, the case 21 is produced, for example, by molding an insulating resin material into a substantially rectangular parallelepiped that can be divided into two pieces, and the end portions 22 a of the divided case member 22 are separated from each other. Space for accommodating a plurality of sets of connection terminals 12 to 14 (connection portion 11) for connecting a plurality of lead-in wires 108 to a single pull-down wire 107 together with the pull-down wires 107 and the lead-in wires 108. Designed to form

ケース部材22は、内装する引下電線107や複数本の引込電線108の並列面の概略延長面で2つ割り可能に形成されており、その長尺な一辺側には、その端辺22a同士を薄肉に連結して開閉可能にするヒンジ部23が成形されている。   The case member 22 is formed so that it can be divided into two on the substantially extended surface of the paralleled surface of the drawn down electric wires 107 and the plurality of drawn-in electric wires 108, and the end sides 22a are arranged on the long side. A hinge portion 23 is formed which is connected to a thin wall and can be opened and closed.

このケース部材22は、図7に示すように、ヒンジ部23以外の三辺側には、その端辺22aの一方側から他方側に向かって延長されているヒダ状部材24が並列するように一体成形されており、このヒダ状部材24の間に引下電線107や引込電線108を進入させて挟み込ませることにより保持可能に作製されている。ここで、本実施形態では、ケース部材22の端辺22aにヒダ状部材24を並列させて引下電線107や引込電線108を位置決め保持する構造を採用するが、これに限るものではなく、例えば、その端辺22aに弾性変形するゴム材料(弾性部材)を連設して引下電線107や引込電線108をその間に挟み込んでその弾性力により保持させるようにしてもよい。   As shown in FIG. 7, the case member 22 has a pleated member 24 extending in parallel from one side of the end side 22 a to the other side on the three sides other than the hinge portion 23. The pull-down electric wire 107 and the pull-in electric wire 108 are inserted between the pleat-shaped members 24 so as to be held between them. Here, in the present embodiment, a structure in which the pleated member 24 is arranged in parallel to the end side 22a of the case member 22 to position and hold the drawn-down electric wire 107 and the drawn-in electric wire 108 is adopted. Alternatively, an elastically deformable rubber material (elastic member) may be connected to the end side 22a so that the pull-down electric wire 107 and the pull-in electric wire 108 are sandwiched therebetween and held by the elastic force.

また、このケース部材22は、端辺22aの一方側から延長されている延長片25の端部の係合穴25aに、その端辺22aの他方側に立設されている係合突起26を引っ掛けることにより、その端辺22a同士を突き合わせて接続端子12〜14(接続部11)を引下電線107や引込電線108と共に内部に収容する状態で閉止することができるようになっている。   In addition, the case member 22 has an engagement protrusion 26 erected on the other side of the end side 22a in the engagement hole 25a at the end of the extension piece 25 extending from one side of the end side 22a. By being hooked, the end sides 22a are brought into contact with each other so that the connection terminals 12 to 14 (connection portion 11) can be closed together with the drawn-in electric wires 107 and the drawn-in electric wires 108.

したがって、電線接続装置10は、引下電線107に複数本の引込電線108を複数の接続部11により適宜導通接続させた後に、ケース21を被せてそのケース部材22の端辺22a同士を付き合わせるように閉じることにより、その引下電線107や引込電線108をヒダ状部材24間に進入させて位置決め保持する状態にすることができる。この後に、例えば、その引下電線107やケース21を腕金105にバインド線などにより巻き付けて固定することにより、引下電線107や引込電線108が接続部11の近傍で揺動して応力集中による断線等を発生させてしまうことなく、電柱101の変圧器103の低圧側からの引下電線107に複数本の引込電線108を導通接続させる作業を完了することができる。   Therefore, the wire connecting device 10 covers the case 21 and covers the ends 22a of the case member 22 after appropriately connecting the plurality of lead-in wires 108 to the pull-down wire 107 through the plurality of connecting portions 11. By closing in this manner, the drawn down electric wire 107 and the drawn-in electric wire 108 can be moved between the pleat-shaped members 24 to be positioned and held. After that, for example, by winding the fixed electric wire 107 and the case 21 around the armor 105 with a bind wire or the like, the drawn electric wire 107 or the drawn electric wire 108 swings in the vicinity of the connecting portion 11 to concentrate stress. The operation of conducting and connecting a plurality of lead-in wires 108 to the pull-down wire 107 from the low-voltage side of the transformer 103 of the utility pole 101 can be completed without causing disconnection or the like.

そして、その引込電線108を増設する必要がある場合には、引込電線108の容量が許す限り、同一の引下電線107の外被を剥いで接続部11により引込電線108を適宜導通接続することができ、ケース21内が接続部11で一杯になった場合には、別のケース21を準備して同様に取り付けることができる。   And when it is necessary to add the lead-in electric wire 108, as long as the capacity | capacitance of the lead-in electric wire 108 permits, it peels off the jacket of the same pull-in electric wire 107, and carries out the conductive connection of the lead-in electric wire 108 suitably by the connection part 11. When the inside of the case 21 is filled with the connecting portion 11, another case 21 can be prepared and attached in the same manner.

一方、引下電線107に導通接続した引込電線108が不要になった場合には、その接続部11のボルトBとナットNを逆方向に相対回転させて接続端子12〜14間を互いに離隔させることにより外して外被を剥いだ箇所に絶縁処理を施すだけで容易に回収作業を完了することができ、その接続部11も再利用することができる。   On the other hand, when the lead-in wire 108 that is conductively connected to the pull-down wire 107 is no longer necessary, the bolts B and nuts N of the connecting portion 11 are relatively rotated in the opposite directions to separate the connection terminals 12 to 14 from each other. Thus, the recovery operation can be easily completed simply by applying insulation treatment to the portion where the outer cover is peeled off and the outer cover is peeled off, and the connecting portion 11 can also be reused.

このように本実施形態においては、引下電線107や引込電線108の導電線107a、108a毎に接続部11の接続端子12〜14をボルトBとナットNにより締め付けて圧接させるだけで導通接続させることができ、また、その締め付けを緩めるだけで導電線107a、108aから接続部11を外すことができる。したがって、引下電線107に複数本の引込電線108を容易に導通接続させる電線分岐装置として利用することができ、その導通接続の解消も容易に行うことができるとともに、その導通接続の解消時には電線を切断する必要はなく、また、その接続端子12〜14も再利用することができる。   As described above, in the present embodiment, the connection terminals 12 to 14 of the connection portion 11 are electrically connected by simply tightening the connection terminals 12 to 14 of the connection portion 11 with the bolts B and nuts N for each of the conductive wires 107a and 108a of the lead-in wire 107 and the lead-in wire 108. In addition, the connecting portion 11 can be removed from the conductive wires 107a and 108a only by loosening the tightening. Therefore, it can be used as a wire branching device for easily conducting and connecting a plurality of lead-in wires 108 to the drawn-down wire 107, and the conduction connection can be easily eliminated. The connection terminals 12 to 14 can be reused.

ここで、本実施形態では、3枚一組の接続端子12〜14の間に引込電線108や引込電線108の導電線107a、108aを収装させて圧接させることにより導通接続する構造に設計した場合を一例に説明するが、これに限るものではなく、4枚以上の接続端子を重ねて導電線にそれぞれの間で圧接接続させるようにしてもよく、この場合には、外側の接続端子だけでなく、その間の共通の接続端子も安定した状態で導電線を収装させた状態にすることができるように変形させても良いことは言うまでもない。この場合には、例えば、1本の引下電線107に対して別個の引込電線108を1箇所の接続部で導通接続させることもでき、ケース21内が接続部11で見掛け上一杯になった場合でも、別のケース21を増設することなく、さらに引込電線108の増設が発生するまで、一時的な応急処置的に分岐接続するなど柔軟に対応することができる。   Here, in the present embodiment, the lead wire 108 and the conductive wires 107a and 108a of the lead wire 108 are accommodated between the connection terminals 12 to 14 in a set of three pieces so as to be in a conductive connection structure. The case will be described as an example, but the present invention is not limited to this, and four or more connection terminals may be stacked and pressure-welded to the conductive wires between them. In this case, only the outer connection terminals may be used. In addition, it goes without saying that the common connection terminals between them may be modified so that the conductive wires can be accommodated in a stable state. In this case, for example, a separate lead-in wire 108 can be conductively connected to one pull-down wire 107 at one connecting portion, and the inside of the case 21 is apparently filled with the connecting portion 11. Even in such a case, it is possible to flexibly cope with such a case where a branch connection is temporarily made as a temporary measure until a further extension of the lead-in wire 108 occurs without adding another case 21.

また、本実施形態においては、2個のナットNをボルトBに螺合させるダブルナットにして外れることを制限するようにしているが、これに限るものではなく、例えば、外れ防止のキャップをボルトBの先端に取り付けるようにしてもよいことは言うまでもない。   Further, in the present embodiment, the two nuts N are screwed into the bolts B to restrict the detachment, but the present invention is not limited to this. For example, a cap for preventing the detachment is bolted. Needless to say, it may be attached to the tip of B.
